Hawks on the Nature Reserve at Alameda Point

Red-tailed Hawks are regular visitors to the Nature Reserve on the former airfield at Alameda Point.  The Northern Harrier, another type of hawk, also visits the reserve, but are fewer in number and harder to spot.  

Red tails and harriers both like the wide open space and grassland where they hunt for prey, but they differ in their abilities to hunt.  The red tails rely on keen vision and are able to hunt from great heights and distance.  Harriers, on the other hand, rely on hearing in the same way that an owl does.  The harrier’s face has characteristics similar to an owl that allows it to capture sounds and direct them to their ears.  They have the ability to hear the sounds of small animals moving in the grass.  They fly close to ground, sometimes within 10 feet, methodically moving about listening for movement.  

Occasionally during the least tern nesting season red tails and harriers prey on the terns and have been trapped by the Fish & Wildlife Service and relocated further inland.  Red tails can catch jackrabbits, but harriers might have a tough time with a full-grown rabbit and look instead for small rodents.  

Adding more grassland on the periphery of the Nature Reserve would help the least terns by providing more hunting opportunities for predators away from the nesting site.  These wild and magnificent birds are but two examples of why the Nature Reserve offers unique opportunities for wildlife habitat enhancement.

The two birds below were photographed in September of 2013.

My blog is Alameda Point Environmental Report covering environmental issues from wildlife to cleanup at the former Navy base in Alameda now called Alameda Point. Articles on my blog are frequently printed in the Alameda Sun newspaper. I also host a Twitter site and a Flickr photo site. I hope you find my stories and photos of interest.
